Details and patient eligibility

About

Horizontal ridge augmentation using either cortical bone plate technique or cortico-cancellous block graft was the aim of the study. Bone quality was analyzed histomorphomterically, and horizontal dimensional changes were assessed using CBCT.

Enrollment: 20 patients

Sex: All

Ages: 20 to 50 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• Eligible patients aged 18 years or older with partial edentulism of the mandible
• The residual ridge width must be 4 mm or less
• Intra-oral donor sites should be available in the external oblique ridge and symphyseal area

Exclusion criteria

• Patients with general contraindications for implant surgery such as uncontrolled diabetes
• Irradiation of the head and neck region
• Intravenous bisphosphonate
• Pregnancy
• Smokers, alcoholics and drug abusers

20 participants in 2 patient groups

Cortical bone plate

Experimental group

Description:

A cortical plate was harvested from the external oblique ridge and split in half. Then one plate was fixed at a distance from the atrophied ridge and autogenous bone chips were used to fill the gap between the plate and the ridge.

Treatment:

Procedure: Split-block technique

Cortico-cancellous block graft

Active Comparator group

Description:

A cortico-cancellous block graft was harvested from the symphysis of the mandible and fixed to the atrophied ridge.

Treatment:

Procedure: Cortico-cancellous block graft
